2008-10-31mac80211: remove rate_control_clearJohannes Berg
"Clearing" the rate control algorithm is pointless, none of the algorithms actually uses this operation and it's not even invoked properly for all channel switching.

We have to be careful if multiple "control frames" are passed in a very short intervals to the device's firmware. As p54_assign_address always put them into same memory location.

2008-10-31airo: Kill directly reference of netdev->privWang Chen
We have some reasons to kill netdev->priv: 1. netdev->priv is equal to netdev_priv(). 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously netdev_priv() is more flexible than netdev->priv. But we cann't kill netdev->priv, because so many drivers reference to it directly. OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug", and I want to kill netdev->priv later, I decided to convert all the direct reference of netdev->priv first. In this driver, I don't simply use netdev_priv() to replace netdev->priv. The reason is: Pointer netdev->priv was changed in this driver, but it shouldn't. Because the memory was allocated when alloc_netdev() and netdev->priv should always point to that memory. So I use netdev->ml_priv to replace netdev->priv. After replacing, both ai and ai->wifidev->ml_priv point to the same memory. Signed-off-by: Wang Chen <wangchen@cn.fujitsu.com> Cc: John W.

2008-10-31rtl8187: add short slot handling for 8187BHerton Ronaldo Krzesinski
This change adds short slot handling for 8187B variant of rtl8187 chips. Some things to note about changes done: * Values used are chosen to met 802.11-2007 spec. This raised a question about SIFS value used with 8187L: 0x22 (34) doesn't match any spec value. For now just don't change 8187L, but is something to be looked at. * On 8187B, the location of EIFS register is at the same place as BRSR+1 of struct rtl818x_csr. Unfortunately there is no clean way to accomodate 8187B differences currently, just use address of BRSR+1 and comment about it. The same thing happens for Ack timeout register, that is on CARRIER_SENSE_COUNTER location of 8187L. The eifs and ack timeout values are in units of 4us. All these registers information was gathered from references being the vendor gpl driver and 8180 datasheet, unfortunately there is no information about this on 8187B datasheet. Also the ack timeout value was inspired by the same calculation as done on rt2x00. Signed-off-by: Herton Ronaldo Krzesinski <herton@mandriva.com.br> Signed-off-by: John W.

2008-10-31mac80211: rewrite HT handlingJohannes Berg
The HT handling has the following deficiencies, which I've (partially) fixed: * it always uses the AP info even if there is no AP, hence has no chance of working as an AP * it pretends to be HW config, but really is per-BSS * channel sanity checking is left to the drivers * it generally lets the driver control too much HT enabling is still wrong with this patch if you have more than one virtual STA mode interface, but that never happens currently. Once WDS, IBSS or AP/VLAN gets HT capabilities, it will also be wrong, see the comment in ieee80211_enable_ht(). Additionally, this fixes a number of bugs: * mac80211: ieee80211_set_disassoc doesn't notify the driver any more since the refactoring * iwl-agn-rs: always uses the HT capabilities from the wrong stuff mac80211 gives it rather than the actual peer STA * ath9k: a number of bugs resulting from the broken HT API I'm not entirely happy with putting the HT capabilities into struct ieee80211_sta as restricted to our own HT TX capabilities, but I see no cleaner solution for now.

2008-10-31mac80211: provide sequence numbersJohannes Berg
I've come to think that not providing sequence numbers for the normal STA mode case was a mistake, at least two drivers now had to implement code they wouldn't otherwise need, and I believe at76_usb and adm8211 might be broken. This patch makes mac80211 assign a sequence number to all those frames that need one except beacons. That means that if a driver only implements modes that do not do beaconing it need not worry about the sequence number. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2008-10-31gianfar: Fix race in TBI/SerDes configurationTrent Piepho
The init_phy() function attaches to the PHY, then configures the SerDes<->TBI link (in SGMII mode). The TBI is on the MDIO bus with the PHY (sort of) and is accessed via the gianfar's MDIO registers, using the functions gfar_local_mdio_read/write(), which don't do any locking. The previously attached PHY will start a work-queue on a timer, and probably an irq handler as well, which will talk to the PHY and thus use the MDIO bus. This uses phy_read/write(), which have locking, but not against the gfar_local_mdio versions. The result is that PHY code will try to use the MDIO bus at the same time as the SerDes setup code, corrupting the transfers. Setting up the SerDes before attaching to the PHY will insure that there is no race between the SerDes code and *our* PHY, but doesn't fix everything. Typically the PHYs for all gianfar devices are on the same MDIO bus, which is associated with the first gianfar device. This means that the first gianfar's SerDes code could corrupt the MDIO transfers for a different gianfar's PHY. The lock used by phy_read/write() is contained in the mii_bus structure, which is pointed to by the PHY. This is difficult to access from the gianfar drivers, as there is no link between a gianfar device and the mii_bus which shares the same MDIO registers. As far as the device layer and drivers are concerned they are two unrelated devices (which happen to share registers). Generally all gianfar devices' PHYs will be on the bus associated with the first gianfar. But this might not be the case, so simply locking the gianfar's PHY's mii bus might not lock the mii bus that the SerDes setup code is going to use. We solve this by having the code that creates the gianfar platform device look in the device tree for an mdio device that shares the gianfar's registers. If one is found the ID of its platform device is saved in the gianfar's platform data. A new function in the gianfar mii code, gfar_get_miibus(), can use the bus ID to search through the platform devices for a gianfar_mdio device with the right ID. The platform device's driver data is the mii_bus structure, which the SerDes setup code can use to lock the current bus.
